BOOKBINDERS RASPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,965, dated April 7, 1896. Application filed August 12 1895. serial No. 559,054. (No model.)

To aZZ whom it may concern.-

Be it known that we, EDWARD J. CAMP- BELL and PATRICK J. HAGGERTY, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Rasping-Machine, of which the following is a full, clear, and exact description.

The invention relates to book-making machinery; and its object is to provide a new and improved rasping-machine, more especially designed for rasping or roughening the edges of the leaves of books, papers, cardboard, &c., and to produce an uneven ragged or jagged The invention consists of certainparts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 1. Fig. 4 is a rear elevation of thejcarriage for supporting the work, and Fig. 5 is an an inverted plan view of a guide-bar.

In making books and other similar articles it is desirable to mechanically produce ragged or jagged edges on the front and bottom edges of the book to imitate the natural rough edge of the leaves of hand-made paper used for some styles of books. To produce this result,

it was heretofore necessary to rasp the edges. of the book by hand previously to applying.

the covers, but this process is rather tedious and unsatisfactory. Now in order to s uccessfully treat a number of books (previously to attaching the covers) to produce the abovementioned result ina very simple, cheap, and effective manner is the object of the invention presently to be described in detail.

The improved rasping-machine is provided with a suitably-constructed frame A, in the upper part of which is journaled a transverselyextending shaft B, carrying fast and loose pulleys 0, connected by belt with other machinery for impartinga rotary motion to the said shaft 13. On the front end of the latter is secured a crank-disk D, connected by a pitman E with a slide F, mounted to reciprocate vertically in suitable guideways A, forming part of the main frame A. On the slide F are secured a series of vertically-disposed rasping-plates G, G and G of which the rasping-plate G has its side edge curved or beveled rearwardly, as plainly indicated in Fig. 3, to permit of readily passfront of the main frameAby causing the said carriage to slide on guideways J and J, of which the guideway J is fixed to the guideways A and the other guideway J is secured on two transversely-extending bars J fitted to slide on the sides of the main frame A. Each bar J 2 is provided with a rack J 3 (see Fig. 1,) in mesh with a pinion J and the two pinionsone at each side of the machineare secured on a single shaft J journaled in suitable bearings in the frame A.

On one end of the shaft J 5 is secured ahandwheel J adapted to be turned by the operator to move the bar J 2 inward or outward to bring the guideway J nearer to or farther from the other guideway J, according to the width of the carriage I carrying the work. It is understood that for different-sized work a different-sized carriage I is employed.

In order to fasten the bars J 2 in place after the adjustment is made for a particular-sized carriage, We provide each bar with a longitudinally-extending slot J through which passes a clamping-bolt J engagin the frame A and serving to clamp each bar J 2 in place.

The carriage I is in the form of a box, open at the top and on two adjacent sides, so that the leaves of a book, papers, cardboard,-and the like placed in the box project on that side nearest to the rasping-plates G G G G s0 that when the carriage is moved past the rasping-plates While the latter reciprocate the edges of the leaves are cut by the roughened surfaces of the plates.

The movement of the carriage I with the work is from right to left, so that the leaves readily pass against the roughened surfaces of the rasping-plates, being first operated on by the beveled. edge of the first rasping-plate G. The leaves, papers, cardboard, &c., are held in place in the carriage I by a presserfoot 1, adapted to be engaged by a cam-lever 1 fulcrumed in the head I of a screw 1 screwing in a bracket 1, secured to the carriage I, as is plainly shown in Figs. 2 and 4.

In order to prevent the carriage from being pulled upward on the upstroke of slide F, carrying the rasping-plates G G G G we provide a yielding bar K, mounted to slide vertically in guideways A attached to the guideways A. This bar K extends in front of the rasping-plates and is hung on screwrods K, adapted to be raised or lowered by their nuts K as will be readily understood by reference to Figs. 1 and 2. Springs K are coiled on the screw-rods K and rest with their upper ends on the bearings for the screwrods and at their lower ends rest on nuts K screwing on the screw-rods K. By this arrangement the bar K is yieldingly mounted and can be adjusted vertically to suit the different heights of the carriages I.

In the under side of the bar K are journaled a series of friction-rollers K adapted to engage the top surface of the presser board or foot I of the carriage I, so that the upward movement of the rasping-plates will not lift the carriage off the guideways at the time the said rasping-plates engage the edges of the work H contained in the carriage I.

On the front of the main frame A is arranged a box L, into which drop the cuttings produced by the rasping-plates in cutting the edges of the work.

The operation is as follows: The books are placed in the carriage so as to rest with the back and top edges on the corresponding sides of the carriage and to project the front and bottom edges of the book beyond the correspondin g sides of the carriage I. The presser board or foot I is now placed on the top leaf of the book and the operator brings the camlever down upon the presser-board to securely hold the book in place. The carriage is now placed in the right-hand end of the guideways J J with one of the projecting sides to the rear-that is, toward the rasping-plates. hen the shaft 13 is in motion, a continuous reciprocating movement is given to the rasping-plates G G G G", and the operator in pushing the carriage I containing the work H from the right to the left brings the projecting edges of the work successively against the roughened faces of the rasping-plates G G G G so that the edge of the work is acted on and is ragged or jagged, it being understood that the graduated rasping-plates first cut the edges roughly and finally finish off by the finer graduated raspingplate G WVhen one side of the work has thus been treated, the carriage is removed from the left end of the guideways and lifted to the righthand end thereof and given one-quarter turn, so that the other side or bottom of the book is next to the rasping-plates. The above-described operation is then repeated-that is, the carriage I is moved to the left on the guideways J J to bring the Work to the rasping-plates for roughening the ct ges of the leaves on this side of the books under treatment. As the carriage is made square at the bottom, the guideways need not be adjusted for the particular carriage unless differentsized books are treated and placed on a larger or smaller carriage.

\Ve do not limit ourselves to the particular construction of the machine shown and described, as it is evident that the same can be varied without deviating from our invention. For instance, the rasping-plates, instead of being mounted on a slide to reciprocate, may be placed or formed on a revoluble cylinder to produce the same result.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A rasping-machine of the class described, provided with movable, graduated raspingsurfaces, and means for moving the work to and past the said surfaces, to cause the latter to roughen the side of the work, substantially as shown and described.

2. A raspingqnachine of the class described, provided with a series of graduated reciproeating rasping-plates, substantially as shown and described.

A rasping-machine of the class described, comprising a carriage adapted to contain the work and mounted to travel, and a series of reciprocating, graduated rasping-plates adapted to engage the edge of the work as the carriage is moved past the said raspingplates, substantially as shown and described.

4. A rasping-machine of the class described, comprising a carriage adapted to contain the work and mounted to travel, a series of reciprocating, graduated rasping-plates adapted to engage the edge of the work as the carriage is moved past the said raspingplates, and a yieldingly-mounted bar adapted to engage the top of the said carriage, to hold the latter 011 the guideways during the upstroke of the rasping-plates, substantially as shown and described.

5. A rasping-machine, comprising a reciprocating series of graduated rasping-plates, a carriage adapted to contain the work, and adapted to be moved past the said raspingplates, an adjustable guideway for the said carriage, and a yieldingly-mountcd bar adapted to engage the top of the carriage, substantially as shown and described.

(5. A device of the character described comprising a frame, a series of graduated rasping on said slide and adapted to act successively on the Work, and means for moving the Work transversely to the path of the said slide, substantially as specified.

8. A device of the character described, comprising a frame, a rasping device movable thereon, means for actuating said rasping device, guides arranged transversely to the path of the rasping device, one guide being movable toward the other,'a locking device for the movable guide, a carriage movable along said guides, and a yielding bar on the frame to engage the carriage atapoint opposite said guides, substantially as specified.
